Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Honeywell 58C11K is determined by the following critical parameters:

Core Compatibility Parameters:

• Resistance value: 1k Ohm (exact match required)
• Taper type: Linear (exact match required)
• Termination style: Solder Lug (exact match required)
• Mounting type: Panel Mount (exact match required)
• Bushing thread: 3/8-32 (exact match required)
• Number of turns: 1 (exact match required)
• Actuator diameter: 0.250" (6.35mm) (exact match required)

Allowable Variation Parameters:

• Power rating: Substitute must equal or exceed the original 4W specification
• Tolerance: Substitute tolerance may differ from ±5%
• Body size: Minor dimensional variations acceptable if mounting interface remains compatible
• Actuator length: Variation acceptable if panel clearance permits

The CTS Electrocomponents 026TB32R102B1A1 meets all core compatibility requirements and exceeds the power rating specification, qualifying as a direct substitute.

Engineering Selection Recommendations

The CTS Electrocomponents 026TB32R102B1A1 is a qualified substitute for the obsolete Honeywell 58C11K based on the following engineering criteria:

Functional Equivalence: Both components share identical core specifications for resistance value, taper type, rotation range, termination style, and mounting interface. The 1k Ohm linear wirewound construction with 300° rotation and solder lug termination ensures functional compatibility in existing circuit designs.

Power Rating Enhancement: The CTS substitute provides 5W power rating compared to the original 4W specification, representing a 25% increase in thermal capacity. This enhancement provides additional design margin without introducing incompatibility.

Regulatory Compliance: Both components maintain RoHS compliance and REACH unaffected status. The CTS part achieves ROHS3 compliance, meeting current regulatory requirements for new designs and manufacturing processes.

Product Availability: The Honeywell 58C11K is obsolete with limited remaining inventory. The CTS 026TB32R102B1A1 maintains active production status with 1627 units in stock, ensuring supply chain continuity for both replacement and new production applications.

Tolerance Consideration: The CTS substitute exhibits ±20% tolerance compared to the original ±5% tolerance. Applications requiring tighter tolerance control must evaluate this specification difference against circuit performance requirements.

Frequently Asked Questions (FAQ)

Q: Can the CTS 026TB32R102B1A1 directly replace the Honeywell 58C11K in existing assemblies?

A: Yes. The CTS substitute maintains identical mounting interface specifications (3/8-32 bushing thread, 0.250" actuator diameter), electrical characteristics (1k Ohm linear wirewound), and termination style (solder lug). Physical installation and electrical connection are directly compatible.

Q: What is the significance of the 5W power rating on the CTS substitute versus the 4W original?

A: The higher power rating indicates greater thermal dissipation capacity. The substitute can safely handle the same power levels as the original while providing additional thermal margin. This does not create incompatibility; it represents an enhancement.

Q: Does the ±20% tolerance of the CTS part affect circuit performance?

A: Tolerance impact depends on circuit application. Applications with tight resistance requirements must evaluate whether ±20% tolerance meets performance specifications. The original ±5% tolerance provides tighter control. Circuit designers should verify tolerance requirements against application specifications.

Q: Are there physical dimension differences between these components?

A: The CTS substitute has a smaller body diameter (0.937" versus 1.690") and shorter actuator length (1.000" versus 2.000"). These differences do not affect the mounting interface but may impact panel clearance and operator ergonomics. Verify panel cutout dimensions and actuator accessibility for your specific application.

Q: What is the inventory status for these components?

A: The Honeywell 58C11K is obsolete with 700 units remaining in stock. The CTS 026TB32R102B1A1 is actively manufactured with 1627 units available. For new designs and long-term production, the CTS component ensures supply continuity.

Q: Are both components RoHS compliant?

A: Yes. The Honeywell 58C11K is RoHS compliant. The CTS 026TB32R102B1A1 achieves ROHS3 compliance, meeting current regulatory standards. Both components are REACH unaffected.
